Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947812, here are decompositions:

29 + 947783 = 947812
59 + 947753 = 947812
71 + 947741 = 947812
83 + 947729 = 947812
101 + 947711 = 947812
191 + 947621 = 947812
233 + 947579 = 947812
251 + 947561 = 947812

Showing the first eight; more decompositions exist.
